Thanks; it looks like my understanding is outdated, though note the following caveats: SMIC 7nm: https://www.tomshardware.com/news/china-chipmaker-smics-7nm-process-is-reportedly-copied-from-tsmc-tech https://www.tomshardware.com/news/china-chipmaker-smics-7nm-... (ignore the journalist-speculative headline, but pay attention to the following) > "This low-volume production product may be the steppingstone for a true 7nm process that incorporates scaled logic and memory bitcells. Since bitcoin miners have limited RAM requirements, they likely do not feature the typical bitcell memory that the true 7nm technology definition requires (both scaled logic and bitcell adoption). This chipset likely demonstrates the logic part but not the bitcell aspect," said TechInsights. Biren: this looks to be diffused by TSMC.
